Anek Image Optimizer is a professional-grade image optimization plugin built for speed, privacy, and flexibility. It is 100% free, runs entirely on your own server, and ships with zero telemetry — your images never leave your infrastructure.

Multi-Library Engine

Most optimization plugins lock you into a single backend. Anek supports three simultaneously:

  • Libvips — the fastest image processing library available (the same engine used by Cloudinary and Sharp.js). Runs as a native binary for extreme throughput and minimal memory usage.
  • Spatie Image — PHP-native library with selectable GD or Imagick drivers.
  • Intervention Image — alternative PHP library with GD or Imagick drivers.

Next-Gen Format Output

  • Compress original JPEG and PNG files in-place.
  • Generate WebP sidecar files alongside originals.
  • Generate AVIF sidecar files alongside originals.
  • All three outputs from a single source image, in one operation.
  • Built-in Apache/LiteSpeed .htaccess rules and Nginx config snippets for zero-PHP server-level delivery — browsers that support AVIF or WebP get them automatically; others fall back gracefully.

Deep WordPress Integration

  • Optimize directly from the Media Library — per-image buttons appear in attachment details.
  • Bulk optimization — compress your entire media library in one click with real-time progress.
  • Auto-optimize on upload — new images are processed the moment they are added.
  • File-system deep scanner — discovers and optimizes images outside wp-content/uploads, including theme images, plugin assets, and custom directories.

Preserve Originals

Toggle on “Preserve Originals” and a backup copy of every image is kept before compression. Restore any image to its original state at any time with zero data loss.

Quality & Exclusion Controls

  • Adjustable quality slider (0–100) per compression run.
  • Strip EXIF metadata to reduce file size further.
  • Set a minimum file size threshold to skip images already small enough.
  • Exclude specific paths from bulk operations.

100% Free, Zero Telemetry, Fully Self-Hosted

  • No data leaves your server. All processing happens locally.
  • Zero telemetry — no usage tracking, no analytics, no phone-home requests.
  • No API keys, no accounts, no subscriptions.
  • Full feature set available from day one with no freemium locks or upsells.
